What to Expect During A Backflow Test

  • Upon locating the backflow device, we ensure readiness with the appropriate forms for any agreed-upon tests. The backflow test initiation involves meticulous utilization of various tools and gauges to meticulously assess any pressure differentials within the backflow device.
  • In the majority of cases, the device functions flawlessly and passes the test without issue. However, should a failure occur, our seasoned testers adeptly address the situation by disassembling the device to remove any debris obstructing the valves. Over our years of experience, we’ve encountered an array of obstructions, from tennis balls to large rocks, promptly resolving such issues.
  • Equipped with a comprehensive inventory of spare parts, we are fully prepared to address any necessary repairs on-site. Subsequent to disassembly, resetting the tamper switch is undertaken as part of our meticulous process.
  • Before departing, we consistently ensure to brief the property owner on the completed tasks and any forthcoming visits.
